PURPOSE:To make the thermal welding method available in a small type battery, with the workability improved, by means of connecting poles after a thermal welding work between battery jar and cover without making a connection between plate groups within the battery jar. CONSTITUTION:With a plate group 3, 3' inserted into a battery jar 1, a thermal plate 8, having a hole 8a, 8a' for the top part of a pole 4, 4' to engaged, is arranged between the battery jar 1 and a cover 5, with the both molten, then with the thermal plate 8 removed, the battery jar 1 and the cover 5 are press attached to each other, simultaneously with the pole top part made protruding into a concaved part 5a of the cover top fac. Subsequently a connector 6 is engaged to be installed to the pole 4, 4' with a connection made between the pole groups 3, 3'. And then an injection molding metal mold 11 is placed on top face of the battery, with a synthetic resin injected to the concaved part 5a of the cover top face and its concaved part made filling, as well as with the pole 4, 4' and the connector 6 perfectly fixed, simultaneously a sealing unit 7, for ensuring a liquid tightness between the both pole groups 3, 3', is constructed in one unit. |
